Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to FIG. 1-2, the utility model the following technical schemes are provided: a kind of external drive formula move along a straight line electric cylinder,
Including stepper motor 1, sliding cylinder body 2, sliding nut 3, hollow shaft 4, stepper motor 1, sliding cylinder body 2, mounting plate 6 pass through spiral shell
Bolt is fixedly connected, and one end of stepper motor 1 is provided with sliding cylinder body 2, and there are four recessed for the circumferential surface setting of sliding cylinder body 2
Platform 21, the interval angles between every two concave station 21 are 90 degree, and the inside of sliding cylinder body 2 is close to the setting of one end of stepper motor 1
There is a sliding nut 3, there are four groove 31, the interval angles between every two groove 31 are for the circumferential surface setting of sliding nut 3
90 degree, what one end of sliding nut 3 was located at stepper motor 1 is internally provided with hollow shaft 4, hollow shaft 4 through sliding cylinder body 2,
Locating slide sleeve 5, mounting plate 6, and hollow shaft 4 protrudes from mounting plate 6 far from one end of stepper motor 1, the inside of sliding cylinder body 2 is remote
One end from sliding nut 3 is provided with locating slide sleeve 5, and sliding cylinder body 2 is provided with mounting plate 6 far from one end of stepper motor 1；
